CIRCIlLATING' DEVICE.

To all whom it may concern:

Whilemy: invention provides a novel steam engine and novel connections, whereby, among other results, the mechanical circulation of a fluid in a closed system may be accomplished, the particular object of my invention is to provide means for causing such circulation in a car-heating system, and especially to provide such means so. that the system shall be self-contained in all respects. These and such other objects as may hereafter appear are attained by my invention, a convenient applicationof which to a car heating system is shown in the accompanying drawings, in whichl v Figure 1 v indicates diagrammatically a typical hot-water system for heating passen Fig. 2 shows an'enlargcd sectional detail of a circulating device, embodyinginy invention.

rise in temperature of the water throughout the circulatmg system.

After the temperature of the water within the coil 6, the pipe 11, the chamber 12'and j the riser 13, has reached acertain point, the 5 water will tend to freely circulate throughout the system and. as the necessity for a forced circulation ceases. there will be a less rapid condensation of steam within the pipe 5. Consequently, as the steam'within the pipes 3 and 5 arrives at an approximately uniform temperature and pressure, the motor will ceaseto operate, but whenever,

from any cause, there is a material drop in' the temperature of the water in any part of the circulating system there will be a correspondingly rapid increase of condensation of steam within the compound coil 6, and the motor'and propeller will again be broughtinto action. When, however, the steam' heater is not used and the coil 6 is heated by means .of a fire within the heater 10, while the motor and propeller may remain inactive, they will afford no objectionable obstruction to the water, and the heated column of water will be free to circulate through the'chamber 12 and between the blades of Such, in brief is the operation of my device, the detailed construction of which, as shown in the drawings, is as follows:

Referring particularly to Fig. 2, it will be noted that steam from'the pipe 3 enters the steam chamber in a box A which is provided on one side of the motor casing 4. Extending axially through the box Ais a shaft B,

extending outwardly through a stufling-box OJ This shaft B extends into and across the motor casing 4 and is shown as journaled at D in said casing. The shaft B has preferabl with a collar or flange 7)} The inner end of -the box A is closed by a cap E, through whichthe shaft B extends. and within which it may be journaled ,ifdesired. Loosely mounted upon the shaft B, and 3 between the flange 7) and the cap E. a l

The shaft B is hollow from the interior of the box A to the end which is journaled at D. and prmsidcd with a perforation or passage G conne ting the interior of the shaft with the nterior ol the Mix A.

outer ends, through which they discharge into the interi r of the 'asing f. The haft p"'cfcr.-ll.-l proyidcd with uH enlarged clizHul-ci' with. whi h the motor arms ll and f are connected.

some longitudinal play. and is provided Mounted upon the shaft B is a fly-wheel J. ,The motor arms H are. bent to discharge towards the angle formed by the wall 4 with the wall t of the casing 4, in or across which angle are arranged a plurality of corrugationsor pockets 4, the wider faces of which extend in such a plane that the jets discharged from the bent ends oft-he motor arms H will strike ertically against said faces, and so as to force-the shaft B towards the bearing D, as well as to rotate the shaft B. The discharge ends of the motor arms I are also bent. but are preferably bent in the plane of rotation of the arms I. and so as to impinge against a plurality of pockets 4. proyided on the interior of the casing 4, the shorter walls of which pockets are substantially radial to said casing and are connected by long, inclined, or curved, walls, "which connect the base of-one short wall with the apex of the next,'so that the jets projected from the motor arms I will impinge most directly against the short radial walls, thusexerting the highest efficiency, in rotatingthe shaft B. As a result of this construction. the force exerted by the jets projected from the arms H, and the ]')10SS111 of steam within the box A against the flange 1), will tend to force the shaft B towards the bearing D and to compress the packing washer or ring F between the flange 5 and the cap E, thereby suflicientl y packing the joint between the interior of the box A and the interior of the casing 4t.

Steam entering the box A. through the pipe 3, will have no outlet, except through the opening G, into the interior of the shaft B, and thence into the chamber 7). These passages are preferably so proportioned that in its initial flow steam will enter the cham her I) much more rapidly than it will flow out I through the arms H and I. so that a body of l steam under pressure will gather within the the arms ll. l. will. in a familiar manner. cau e the rotation of Ho shaft B and. as the parts are so propoltiollctl that the arms ll. i. will just safely clear the walls of the pockets 4" and -1 the llIlPlllfjjlllFj}:Blltl partial huddling of the steam wit bin said poclLt-ls will increase the motor cilicicm-y of the steam. in causing thc rotation of the shaft B.

Q. 'This rotation of the propeller bladesiQ, ,asihefore explained, forces water out o flthe pronellerchainber 12 through. the

pipe 13,.and draws Water into the propeller chamber 12 through the pipe ,11, and the forced I circulation, is established.

I Itwill thus be seen that with the described embodiment of my inyention, in its initial operation the motor carriesno load except the friction incident to its ownoperation,

and acquires no load until it has aoquir'eda speed which brings the friction clutch. into operation, such operation of. the friction clutch heingjto gradually put theloa-d ion the 'motor until the apparatus is running at full speed.

It will also be noted that the high speed of rotationacquiredby the fly-Wheel before the friction clutch is inoperation,

tends to continue the rotation of the motor,

as the load isgradually put on'it by the operation'of the clutch device. But, Whenever the condensation of steam" within thepipe 5 becomes materially slower, because'of the heating of the ater of circulation throughoutv the system, the flow .of steam through the motor arms H, I, will become correspond ingly slower, and the speed of rotation of the motor will gradually decrease until the springs Z overcome the centrlfugalaction of the Weights Z, the clutch is disconnected, and

the propeller ceases to rotate.

On the other hand, whenever the tempera turev of the Water of circulation is materially lowered, the rate of condensation, within the compound coil '6, will increase, the flow of steam through the motor will increase, and the motor will again be put into operation. Ifthe drop in temperature of the water of circulation is suflicient to be really material,

the result will be to produce such an increasing speed of the motor as Will-again connect the clutchand set the propeller in'to operation, thus increasing the speed of circulation of water through the pipes,-and rapidly bringing the water of circulation to the required temperature. v

In Fig. 1 1, I have illustrated another arrangement in which the steam-pipe 5 leads from the motor-casing 4 to ajacket 12 which surrounds the propeller-casing 12,

from which iacket the pipe 5 leads to the coil within the heater 1 0. In this arrangement the acket 5 and the casing 1,2.consti- ,tute a condenser, which is conveniently arranged immediately adiacent to themotorcasing 4, so as to quickly produce an operative difference in pressure between the'pipe 3 and the -pipe 5? tern or, ifv a steam jacket is used,.it matters v ,notwhether the steam-jacket is in thezform of coil surrounding the Water-coil or in the form of a steamacket surrounding the: propeller-casing or in any other wellknown form of, device whereby the heat of the steam. is

imparted to thewater of the circulating systern. The particular formof device used for heating the water is primarilyof no consequence.
